Let the width = x then length = x + 11 inches
Perimeter of a rectangle = 2*width + 2*length so we have the equation:-
( letting P = perimeter , L = length and W = width)
P = 2L + 2W
86 = 2(x + 11)) + 2x
86 = 4x + 22
4x = 86-22 = 64
x = 64 / 4 = 16 inches
Therefore the length of the rectangle = 16 + x
= 16 + 11 = 27 inches Answer
A= l times w. A=14628 and w=12 so length equals 1219 millimeters
C2 = a2 + b2
c2 = 20^2 + 28^2
c2 = 400 + 784
c2 = 1184
c = 34.4
